The MTU (Maximum Transmission Unit) is the size of the largest network packet that can be transferred in a single network transmission without any fragmentation happening.
We have a separate page on testing your [[MTU]].
Sometimes you may have a reason to change the MTU on your windows computer. Here is how.
We will show you how to show the existing MTU, and then how to change it, and then how to revert it back to what it was originally. We're using Windows 10 in this example.

# Click <SyntaxHighlight inline>start</SyntaxHighlight>
# Type <SyntaxHighlight inline>cmd</SyntaxHighlight>
#Enter the command: <SyntaxHighlight inline>netsh</SyntaxHighlight>
#Then: <SyntaxHighlight inline>interface</SyntaxHighlight>
#Then: <SyntaxHighlight inline>ipv4</SyntaxHighlight>
#Then: <SyntaxHighlight inline>set subinterface "Ethernet" mtu=1320</SyntaxHighlight>
#Then: <SyntaxHighlight inline>exit</SyntaxHighlight>
The screenshot shows all these commands being run...
